Song Chi's point is that Zhou Yun doesn't need to directly clash with Yao Yuanfeng.
Right now, there's already some awkwardness between Zhou Yun and Yao Yuanfeng because of the success of "Two Tigers" Part Two. If she goes to talk to Yao Yuanfeng about the filming of "Female Assassin" at this time, it will be easy for Yao Yuanfeng to develop other thoughts, even if Zhou Yun has no such intentions.
For instance, Yao Yuanfeng might think Zhou Yun is exploiting the situation.
Zhou Yun put aside the idea of calling Yao Yuanfeng.
As Song Chi said, there's indeed no need.
Zeng Yeng looks amiable and easy to talk to, but in reality, it's not quite so. Zhou Yun had a deep understanding of this during the next few days of interacting with her.
The first few days of shooting involved filming some less significant scenes.
But what's considered less significant is only in terms of the main storyline of this movie.
